U.S. Park Police officer used an electronic stun gun on an Occupy DC protester. Police say he was tearing down fliers warning protesters about the ban on camping in McPherson Square. Police also said the unidentified man was charged with disorderly conduct. The arrest took place shortly after noon Sunday. It is reported that after the incident the man had a seizure, and was then refused medical treatment. A park police spokesman said the man became “aggressive and confrontational” when officers tried to arrest him and that is why the stun gun was used.
